Investigation of Distribution, Population Development, Flight Period, Infestation and Damage Rate of Cherry Fruit Fly, Rhagoletis cerasi L. (Diptera: Tephritidae), Associated with Cherry and Sour Cherry Orchards

This study was carried out to determine the distribution, population development, infestation and damage rate of the Cherry fruit fly, Rhagoletis cerasi L. (Diptera: Tephritidae), which harmed the growing of cherries and sour cherries in Erzincan province, Turkey, in 2016-2018. The main materials of this study were the adult and preadult periods of R. cerasi. Attractive Rebell traps with ammonia salt, insect aspirator, culture cages, etc., were also used. The investigations had four steps: determination of the distribution, population development, flight period, and infestation and damage rate of the cherry fruit fly. Sampling was carried out according to the Lazarov and Grigorov (1961) method in randomly selected orchards. According to the results of the study, it was determined that the pest distributed in the cherry and sour cherry trees in all locations where the study was carried out in the Central and uzumlu districts of Erzincan. The population development of the Cherry fruit fly was found to be highest in the orchards in the uzumlu district with coordinates 39.715490 degrees 39.704287 degrees (164 adults) and 39.713162 degrees 39.679763 degrees (158 adults) in 2016, coordinates 39.715490 degrees 39.704287 degrees (24 adults) and 39.713162 degrees 39.679763 degrees (48 adults) in 2017, and coordinates 39.715490 degrees 39.704287 degrees (309 adults) and 39.711130 degrees 39.688508 degrees (376 adults) in 2018; among the orchards in the Central district, population development was highest in Ekmekli ([39.750837 degrees 39.354710 degrees] [438 adults]) and Bahcelikoy ([39.751601 degrees 39.361090 degrees] [1404 adults]) in 2016, Elmakoy ([39.790915 degrees 39.357436 degrees] [107 adults]) and Bahcelikoy ([39.751601 degrees 39.361090 degrees] [169.5 adults]) in 2017, and Elmakoy ([39.790915 degrees 39.357436 degrees] [1815.5 adults]) and Bahcelikoy ([39.751601 degrees 39.361090 degrees] [918.5 adults]) in 2018. The adult flight period was found to be 55-78 days, and the infestation rate of the pest was found to be 83.33% in Erzincan province. In addition, it was determined that the damage rate of the pest was between 52.6% and 54.6% in the Central district of Erzincan and between 26.2% and 31.2% in the uzumlu district.

Automated summary
